Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a drive device, a tapping mechanism, and cleaning equipment. Background Technology

[0002] Cleaning equipment, such as mite removers, is a small household appliance with functions such as mite removal, vacuuming, and sterilization. It can clean dust off furniture such as beds and sofas. The core working principle of mite removers is "beating, vacuuming, and sterilization".

[0003] The related technology discloses a mite removal device, including a housing, a roller brush, and a beating device. The roller brush and the beating device are mounted on the housing. The device also includes a drive unit that simultaneously drives the roller brush and the beating device. The drive unit includes a motor, a splined shaft, a first synchronous pulley, a second synchronous pulley, a synchronous belt, and an eccentric shaft. The power output end of the motor is connected to the splined shaft to output power. The splined shaft has a first spline and a second spline. The first spline is connected to the first synchronous pulley via a synchronous belt, and the second spline is connected to the second synchronous pulley via a synchronous belt. The first synchronous pulley drives the roller brush to rotate, and the second synchronous pulley drives the eccentric shaft to rotate. The beating device passes through the housing and is connected to the eccentric shaft. The rotation of the eccentric shaft causes the beating device to reciprocate relative to the housing.

[0004] The aforementioned technologies require two sets of synchronous belts to drive the roller brush and the beating device, which takes up a lot of space. Utility Model Content

[0005] In view of this, the present invention provides a driving device, a tapping mechanism, and a cleaning device to solve the problem of the large space occupied by the driving device of the driving roller brush and the tapping device.

[0006] In a first aspect, this utility model provides a driving device, comprising:

[0007] A dual-axis output motor includes a first output shaft and a second output shaft, wherein the first output shaft is connected to a first pulley;

[0008] A roller brush drive rod is adapted to be connected to a roller brush assembly. The roller brush drive rod is connected to a second pulley, and the second pulley is connected to the first pulley via a transmission belt.

[0009] A transmission assembly, connected to the second output shaft and adapted to connect to a striking plate, is provided, wherein the transmission assembly is capable of converting the rotation of the second output shaft into the movement of the striking plate.

[0010] Beneficial effects: When the dual-axis output motor is working, the first and second output shafts rotate synchronously. The rotation of the first output shaft drives the first pulley to rotate synchronously, which in turn drives the second pulley to rotate via a transmission belt. The second pulley drives the roller brush drive rod to rotate synchronously. The roller brush drive rod is connected to the roller brush assembly, thus driving the roller brush assembly to rotate. The transmission assembly converts the rotation of the second output shaft into the movement of the striking plate. Therefore, a single dual-axis output motor can simultaneously drive the striking plate and the rotation of the roller brush assembly. Since the transmission assembly is directly located between the second output shaft and the striking plate, compared with related technologies, this drive device can reduce the need for a set of synchronous belts, thus reducing the space occupied.

[0011] In one alternative embodiment, the transmission assembly includes an eccentric wheel and a connecting rod. The eccentric wheel is fixed to the end of the second output shaft. A first end of the connecting rod is hinged to the eccentric wheel, and a second end of the connecting rod is hinged to the striking plate. The hinge axis between the connecting rod and the eccentric wheel is offset from the axis of the eccentric wheel.

[0012] Beneficial effects: The transmission assembly includes an eccentric wheel and a connecting rod. The eccentric wheel is fixed to the end of the second output shaft. Therefore, when the second output shaft rotates, it drives the eccentric wheel to rotate synchronously. Since the first end of the connecting rod is hinged to the eccentric wheel and the second end of the connecting rod is hinged to the striking plate, the hinge axis between the connecting rod and the eccentric wheel is offset from the rotation center of the eccentric wheel. Therefore, when the connecting rod rotates, it will move in the up and down direction, driving the striking plate to move up and down to achieve striking.

[0013] In one optional embodiment, the distance between the center of the hinge shaft and the axis of the eccentric wheel is X, where 1mm ≤ X ≤ 6mm.

[0014] In one optional embodiment, the first end of the connecting rod is provided with a first connecting hole, the first connecting hole is provided with a first bearing, the hinge shaft is provided on the eccentric wheel, and the inner ring of the first bearing is sleeved on the hinge shaft.

[0015] And / or, the second end of the connecting rod is provided with a second connecting hole, the second connecting hole is provided with a second bearing, the striking plate is provided with a hinge seat, and the fixing pin is adapted to pass through the hinge seat and be fixed to the inner side of the inner ring of the second bearing.

[0016] Beneficial effects: The first connecting hole houses a first bearing, and the hinge shaft is located on the eccentric wheel. The inner ring of the first bearing is fitted onto the hinge shaft, ensuring smooth rotation of the first end of the connecting rod relative to the hinge shaft. The second connecting hole houses a second bearing, and the striking plate has a hinge seat. A fixing pin passes through the hinge seat and is fixed to the inner side of the inner ring of the second bearing, ensuring smooth rotation of the second end of the connecting rod relative to the hinge seat.

[0017] In one alternative embodiment, the drive device further includes a bracket, on which the motor is mounted, and the first output shaft and the roller brush drive rod are rotatably mounted on the bracket.

[0018] Beneficial effects: By setting up a bracket, the motor is mounted on the bracket, and the first output shaft and the roller brush drive rod can be rotatably mounted on the bracket. Therefore, the entire drive device can be assembled into a whole. Then, the whole is placed in the bottom shell, and the bracket is fixed to the bottom shell, thereby realizing the assembly of the entire drive device.

[0019] In one optional embodiment, the bracket includes a first limiting plate and a second limiting plate disposed opposite to each other, and a first end plate and a second end plate connecting the two ends of the first limiting plate and the second limiting plate. The first output shaft is rotatably disposed on the first end plate, and the dual-axis output motor is mounted on the second end plate and the second output shaft passes through the second end plate.

[0020] Beneficial effects: The first end plate provides limiting support for the first output shaft, while the second end plate serves both to fix the dual-shaft output motor and to provide limiting support for the second output shaft. Furthermore, the dual-shaft output motor is located between the first and second limiting plates, which provide protection and limit its movement.

[0021] In one alternative embodiment, the first end plate is fixed with a third bearing, which is sleeved outside the first output shaft.

[0022] Beneficial effects: The third bearing is sleeved outside the first output shaft and fixed to the first end plate, which can support and limit the first output shaft and ensure that the first output shaft rotates smoothly.

[0023] Secondly, this utility model also provides a slapping mechanism, including the aforementioned driving device, a roller brush assembly, and a slapping plate. The roller brush assembly is connected to the roller brush driving rod, and the slapping plate is connected to the transmission assembly.

[0024] Beneficial effects: When the dual-axis output motor is working, the first and second output shafts rotate synchronously. The rotation of the first output shaft drives the first pulley to rotate synchronously, which in turn drives the second pulley to rotate via a transmission belt. The second pulley drives the roller brush drive rod to rotate synchronously. The roller brush drive rod is connected to the roller brush assembly, thus driving the roller brush assembly to rotate. The transmission assembly converts the rotation of the second output shaft into the movement of the striking plate. Therefore, a single dual-axis output motor can simultaneously drive the striking plate and the roller brush assembly to rotate. Since the transmission assembly is directly located between the second output shaft and the striking plate, compared with related technologies, one set of synchronous belts can be eliminated, thus reducing the space occupied.

[0025] In one alternative embodiment, the circumferential surface of the tapping plate is provided with a sealing strip.

[0026] Beneficial effects: The sealing strip prevents dust from the cleaning surface from entering the beater chamber through the perimeter of the beater.

[0027] In one optional embodiment, the circumference of the tapping plate is provided with a mounting groove, and the sealing strip is installed in the mounting groove.

[0028] Beneficial effect: The installation groove on the periphery of the tapping plate facilitates the installation of the sealing strip.

[0029] Thirdly, this utility model also provides a cleaning device, including a bottom shell and the aforementioned tapping mechanism. The bottom shell is provided with a tapping plate chamber and a roller brush chamber. The tapping plate is movably disposed in the tapping plate chamber, and the roller brush assembly is rotatably disposed in the roller brush chamber.

[0030] Beneficial effects: When the dual-axis output motor is working, the first and second output shafts rotate synchronously. The rotation of the first output shaft drives the first pulley to rotate synchronously, which in turn drives the second pulley to rotate via a transmission belt. The second pulley drives the roller brush drive rod to rotate synchronously. The roller brush drive rod is connected to the roller brush assembly, thus driving the roller brush assembly to rotate within the roller brush mounting cavity. The transmission assembly converts the rotation of the second output shaft into the up-and-down movement of the striking plate within the striking plate cavity. Therefore, a single dual-axis output motor can simultaneously drive the striking plate to strike and the roller brush assembly to rotate. Attached Figure Description

[0050] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0051] The related technology discloses a mite removal device, including a housing, a roller brush, and a beating device. The roller brush and the beating device are mounted on the housing. The device also includes a drive unit that simultaneously drives the roller brush and the beating device. The drive unit includes a motor, a splined shaft, a first synchronous pulley, a second synchronous pulley, a synchronous belt, and an eccentric shaft. The power output end of the motor is connected to the splined shaft to output power. The splined shaft has a first spline and a second spline. The first spline is connected to the first synchronous pulley via a synchronous belt, and the second spline is connected to the second synchronous pulley via a synchronous belt. The first synchronous pulley drives the roller brush to rotate, and the second synchronous pulley drives the eccentric shaft to rotate. The beating device passes through the housing and is connected to the eccentric shaft. The rotation of the eccentric shaft causes the beating device to reciprocate relative to the housing.

[0052] The aforementioned technologies require two sets of synchronous belts to drive the roller brush and the beating device, which takes up a lot of space.

[0053] The following is combined Figures 1 to 13 The following describes embodiments of the present invention.

[0054] According to an embodiment of the present invention, in a first aspect, a driving device is provided, comprising: a dual-axis output motor 1, a first pulley 2, a roller brush drive rod 3, a second pulley 5, a transmission belt 6, and a transmission assembly.

[0055] The dual-axis output motor 1 includes a first output shaft 101 and a second output shaft 102. The first output shaft 101 is connected to a first pulley 2. The roller brush drive rod 3 is adapted to be connected to the roller brush assembly 4. The roller brush drive rod 3 is connected to a second pulley 5. The second pulley 5 is connected to the first pulley 2 through a transmission belt 6. The transmission assembly is connected to the second output shaft 102 and adapted to be connected to the slapping plate 7. The transmission assembly can convert the rotation of the second output shaft 102 into the movement of the slapping plate 7.

[0056] In this embodiment, when the dual-axis output motor 1 is working, the first output shaft 101 and the second output shaft 102 rotate synchronously. The rotation of the first output shaft 101 drives the first pulley 2 to rotate synchronously, which in turn drives the second pulley 5 to rotate via the transmission belt 6. The second pulley 5 drives the roller brush drive rod 3 to rotate synchronously. The roller brush drive rod 3 is connected to the roller brush assembly 4, thus driving the roller brush assembly 4 to rotate. The transmission assembly converts the rotation of the second output shaft 102 into the movement of the striking plate 7. Therefore, a single dual-axis output motor 1 can simultaneously drive the striking plate 7 to strike and the roller brush assembly 4 to rotate. Since the transmission assembly is directly disposed between the second output shaft 102 and the striking plate 7, compared with related technologies, this drive device can reduce the need for a set of synchronous belts, thus reducing the space occupied.

[0057] In one embodiment, the first pulley 2 is interference-fitted with the first output shaft 101.

[0058] In one embodiment, the first pulley 2 and the second pulley 5 are both gears, and both the first pulley 2 and the second pulley 5 mesh with the transmission belt 6.

[0059] In one embodiment, the outer diameter of the second pulley 5 is larger than the outer diameter of the first pulley 2. Since the outer diameter of the second pulley 5 is larger than the outer diameter of the first pulley 2, the rotation speed of the second pulley 5 will be lower than the rotation speed of the first pulley 2. Therefore, the rotation speed of the roller brush assembly 4 will be lower than the rotation speed of the first output shaft 101, thus avoiding the problems of hair entanglement, blanket rolling, and loud noise caused by the excessive rotation speed of the roller brush assembly 4.

[0060] In one embodiment, the transmission assembly includes an eccentric wheel 8 and a connecting rod 9. The eccentric wheel 8 is fixed to the end of the second output shaft 102. The first end of the connecting rod 9 is hinged to the eccentric wheel 8, and the second end of the connecting rod 9 is hinged to the beater plate 7. The hinge axis 801 between the connecting rod 9 and the eccentric wheel 8 is offset from the axis 802 of the eccentric wheel 8.

[0061] In this embodiment, the transmission assembly includes an eccentric wheel 8 and a connecting rod 9. The eccentric wheel 8 is fixed to the end of the second output shaft 102. Therefore, when the second output shaft 102 rotates, it drives the eccentric wheel 8 to rotate synchronously. Since the first end of the connecting rod 9 is hinged to the eccentric wheel 8 and the second end of the connecting rod 9 is hinged to the striking plate 7, and the hinge axis 801 between the connecting rod 9 and the eccentric wheel 8 is offset from the rotation center of the eccentric wheel 8, the connecting rod 9 will move in the up and down direction while rotating, thereby driving the striking plate 7 to move up and down to achieve striking.

[0062] In one embodiment not shown in the figure, the transmission component may include a gear and rack, for example, a gear is connected to the end of the second output shaft 102, the gear meshes with the rack, the rack is connected to the striking plate 7, the rotation of the second output shaft 102 drives the gear to rotate, thereby driving the rack to move up and down, and the rack drives the striking plate 7 to move up and down to achieve striking.

[0063] In one specific embodiment, the eccentric wheel 8 is fixedly mounted on the second output shaft 102 and secured by the first screw 17.

[0064] In one embodiment, such as Figure 3 As shown, the distance between the center of the hinge shaft 801 and the axis 802 of the eccentric wheel 8 is X, where 1mm≤X≤6mm.

[0065] In a preferred embodiment, the X value is 2mm. A 2mm eccentricity can better balance the striking force and the overall vibration of the machine.

[0066] In one embodiment, combined Figure 2 and Figure 5 The first end of the connecting rod 9 is provided with a first connecting hole 901, and a first bearing 10 is built into the first connecting hole 901.

The striking plate 7 is provided with a hinge seat 701, and the fixing pin 12 is adapted to pass through the hinge seat 701 and be fixed to the inner side of the inner ring of the second bearing 11.

[0067] In this embodiment, a first bearing 10 is housed in the first connecting hole 901, and a hinge shaft 801 is mounted on the eccentric wheel 8. The inner ring of the first bearing 10 is fitted onto the hinge shaft 801, ensuring that the first end of the connecting rod 9 rotates smoothly relative to the hinge shaft 801. A second bearing 11 is housed in the second connecting hole 902, and a hinge seat 701 is provided on the striking plate 7. A fixing pin 12 passes through the hinge seat 701 and is fixed to the inner side of the inner ring of the second bearing 11, ensuring that the second end of the connecting rod 9 rotates smoothly relative to the hinge seat 701.

[0068] In a preferred embodiment, a first bearing 10 is provided between the first connecting hole 901 and the hinge shaft 801, and a second bearing 11 is provided between the second connecting hole 902 and the fixing pin 12.

[0069] In one embodiment not shown in the figure, the first bearing 10 and the second bearing 11 may not be provided.

[0071] In one specific embodiment, the hinge seat 701 is provided with a third connecting hole, the fixing pin 12 passes through the third connecting hole and the second connecting hole 902, and is locked by the third screw 19.

[0072] In one embodiment, the drive device further includes a bracket 13, on which a motor is mounted, and on which both the first output shaft 101 and the brush drive rod 3 are rotatably mounted.

[0073] In this embodiment, by setting a bracket 13, the motor is mounted on the bracket 13, and the first output shaft 101 and the roller brush drive rod 3 are rotatably mounted on the bracket 13. Therefore, the entire drive device can be assembled into a whole, and then the whole is placed in the bottom shell 16, and the bracket 13 is fixed to the bottom shell 16, thereby realizing the assembly of the entire drive device.

[0074] In one embodiment, the bracket 13 includes a first limiting plate 1301 and a second limiting plate 1302 disposed opposite to each other, and a first end plate 1303 and a second end plate 1304 connecting the two ends of the first limiting plate 1301 and the second limiting plate 1302. A first output shaft 101 is rotatably disposed on the first end plate 1303, and a dual-axis output motor 1 is mounted on the second end plate 1304, with the second output shaft 102 passing through the second end plate 1304.

[0075] In this embodiment, the first end plate 1303 provides limiting support for the first output shaft 101, and the second end plate 1304 serves both to fix and support the dual-axis output motor 1 and to limit the second output shaft 102. The dual-axis output motor 1 is located between the first limiting plate 1301 and the second limiting plate 1302, which provide protection and limit the movement of the dual-axis output motor 1.

[0076] In one embodiment, such as Figure 1 As shown, the bracket 13 also includes a mounting plate 1305 located on one side of the second limiting plate 1302, and the roller brush drive rod 3 is rotatably mounted on the mounting plate 1305.

[0077] In one embodiment, a third bearing 14 is fixed to the first end plate 1303, and the third bearing 14 is sleeved outside the first output shaft 101.

[0078] In this embodiment, the third bearing 14 is sleeved on the outside of the first output shaft 101 and fixed to the first end plate 1303, which can support and limit the first output shaft 101 and ensure that the first output shaft 101 rotates smoothly.

[0079] According to an embodiment of the present invention, in a second aspect, a striking mechanism is also provided, such as... Figure 6 As shown, it includes the driving device, roller brush assembly 4, and tapping plate 7 provided in the above embodiments. The roller brush assembly 4 is connected to the roller brush drive rod 3, and the tapping plate 7 is connected to the transmission assembly.

[0080] In this embodiment, when the dual-axis output motor 1 is working, the first output shaft 101 and the second output shaft 102 rotate synchronously. The rotation of the first output shaft 101 drives the first pulley 2 to rotate synchronously, which in turn drives the second pulley 5 to rotate via the transmission belt 6. The second pulley 5 drives the roller brush drive rod 3 to rotate synchronously. The roller brush drive rod 3 is connected to the roller brush assembly 4, thus driving the roller brush assembly 4 to rotate. The transmission assembly converts the rotation of the second output shaft 102 into the movement of the striking plate 7. Therefore, a single dual-axis output motor 1 can simultaneously drive the striking plate 7 to strike and the roller brush assembly 4 to rotate. Since the transmission assembly is directly located between the second output shaft 102 and the striking plate 7, compared with related technologies, the need for a set of synchronous belts can be reduced, thus reducing the space occupied.

[0081] Specifically in one embodiment, such as Figure 5 and Figure 10 As shown, the lower surface of the patting plate 7 is wavy, which can increase the patting effect.

[0082] In one embodiment, the patting plate 7 is provided with a sealing strip 15 in the circumferential direction.

[0083] In this embodiment, the sealing strip 15 is provided to prevent dust from the cleaning surface from entering the tapping plate chamber 1601 through the periphery of the tapping plate 7.

[0084] The sealing strip 15 can be made of rubber, silicone, foamed rubber, felt, etc. It is preferred to use felt, which has the advantage of low frictional resistance and will not hinder the up and down movement of the beater 7.

[0085] In one embodiment, the circumference of the slapping plate 7 is provided with a mounting groove 702, and the sealing strip 15 is installed in the mounting groove 702.

[0086] In this embodiment, the installation groove 702 provided on the periphery of the tapping plate 7 facilitates the installation of the sealing strip 15.

[0087] According to an embodiment of the present invention, in a third aspect, a cleaning device is also provided, including a bottom shell 16 and a tapping mechanism provided in the above embodiment. The bottom shell 16 is provided with a tapping plate chamber 1601 and a roller brush chamber 1602. The tapping plate 7 is movably disposed in the tapping plate chamber 1601, and the roller brush assembly 4 is rotatably disposed in the roller brush chamber 1602.

[0088] In this embodiment, when the dual-axis output motor 1 is working, the first output shaft 101 and the second output shaft 102 rotate synchronously. The rotation of the first output shaft 101 drives the first pulley 2 to rotate synchronously, which in turn drives the second pulley 5 to rotate via the transmission belt 6. The second pulley 5 drives the roller brush drive rod 3 to rotate synchronously. The roller brush drive rod 3 is connected to the roller brush assembly 4, thus driving the roller brush assembly 4 to rotate in the roller brush mounting cavity. The transmission assembly converts the rotation of the second output shaft 102 into the up-and-down movement of the striking plate 7 in the striking plate cavity 1601. Therefore, a single dual-axis output motor 1 can simultaneously drive the striking plate 7 to strike and the roller brush assembly 4 to rotate. Since the transmission assembly is directly located between the second output shaft 102 and the striking plate 7, compared with related technologies, the need for a set of synchronous belts can be reduced, thus reducing the space occupied.

[0089] Specifically, during operation, the roller brush assembly 4 is located at the front of the machine. The roller brush rotates and taps the surface being cleaned, which can knock out dust mites from the surface and deep within the surface and then remove them.

[0090] In one embodiment, the striking plate chamber 1601 is provided with a through hole 1603 for the connecting rod 9 to pass through and move.

[0091] In one embodiment, the cleaning device is a mite remover, which also includes an ultraviolet lamp assembly, an air duct assembly, a vacuum motor assembly, and a dust cup assembly.

[0092] In one embodiment, the striking plate 7 and the bottom shell 16 are connected by a guide structure, which is used to guide the movement direction of the striking plate 7.

[0093] In this embodiment, by setting a guide structure, the tapping plate 7 can move smoothly in the vertical direction, avoiding the tapping plate 7 from shaking.

[0094] In one specific embodiment, the guide structure includes a guide post 703 and a guide hole 1604. The guide post 703 is disposed in one of the bottom shell 16 and the beater plate 7; the guide hole 1604 is disposed in the other of the bottom shell 16 and the beater plate 7, and the guide post 703 and the guide hole 1604 are slidably engaged.

[0095] In this embodiment, the guide post 703 and the guide hole 1604 cooperate to allow the tapping plate 7 to move smoothly in the vertical direction, thus preventing the tapping plate 7 from shaking.

[0096] Specifically in one embodiment, such as Figure 10 , Figure 11 and Figure 12 The guide post 703 is located on the beater plate 7, and the guide hole 1604 is located on the bottom shell 16.

[0097] Specifically in one embodiment, such as Figure 12 The roller brush mounting cavity is provided with a through hole 1603 for the connecting rod 9 to pass through and move.
